Pedroia, who was fitted with a custom brace to protect his thumb, took about 25 swings over four sessions. He’ll be re-evaluated throughout the weekend to see if there’s any increased swelling from today’s session, after which the Red Sox will likely make a decision about whether to keep him active or place him on the disabled list.

Pedroia, 28, is hitting .295/.350/.450 with five homers, 21 RBI, three stolen bases and an .800 OPS through 48 games this year. Nick Punto, who went 3-for-4 with a long home run this afternoon, is currently filling in at second base.

Buchholz, 33, was acquired by the Phillies from the Red Sox in December 2016, but he made only two starts before an MRI revealed he had a partial tear of his right flexor pronator mass. He underwent surgery in April and missed the rest of the season.
